Covers all nine stress cases from #25, #15 and #16. The lowest bid is disqualified on two missing health documents and the highest bid is strongest on the SFA's own geographic-preference criterion, so a ranking that cannot represent absence gets the field exactly backwards. Deliberate traps: a planted $400 arithmetic error in a stated total, an unverifiable total whose unit price lives only in the external Excel, an unlabelled exception, a non-priceable exception that is really a conditional withdrawal, and an answered-but-negative response. Second schema finding, surfaced by the validator: R-B6C is a mandatory gate that no response document can establish. Coverage over it is unknowable rather than absent.

Corpus
Source documents for the synthesized response corpus (#30). Archived 2026-08-03 because #22 read them from live URLs and kept nothing — and its ninth hazard was that live procurement PDFs 403 or return bot-challenge HTML without warning.
All seven retrieved successfully; none of the 403s #22 hit recurred.

52 | Grocery, nested rubric, closest to the retail domain. Its price sheet is a separate Excel attachment, which exercises #22's second extraction hazard. |

142 | Richest binding structure — paragraph headings A–M restated verbatim. Has a shortlist-for-interviews stage that exercises the finalist release level. |
Validation artifact — not a solicitation
tarrant-county/rfp.pdf (1pp) is an award tabulation, not an RFP. No
requirements, so nothing can be written against it. What it holds is the only
real published outcome in the set:
Evaluation Criteria Max Five Star Selrico Trinity
Management & Support Staff 25 15.84 15.00 16.36

PRIMARY SECONDARY ALTERNATE
Three vendors inside 1.19 points. This is what ranking arithmetic gets checked against — the only place in the corpus where our maths can be wrong in a way that is detectable rather than self-consistent. It is also concrete evidence for storing fractional scores: rounding erases this result entirely.

Corrections to #22's record
- SLC Airport is 142pp, not 55pp.
- Maryland MBE forms are 27pp, not 20pp.
- Tarrant County was described as a document with a score tabulation; it is only a tabulation, which changes its role in the corpus.
